It is considered that in a suitable storage site, CO₂ will be stored by physical or geochemical trapping or a combination of both. Physical trapping includes: stratigraphic trapping, when the CO₂ is held below a low-permeability seal (cap rock); structural trapping, where CO₂ is trapped by physical structures such as those formed by faults and folds of the rock; or hydrodynamic trapping in saline formations, where fluids migrate very slowly and the buoyant CO₂ migrates upwards to the top of the formation.  2, record 1, English, - physical%20trapping

Le piégeage physique, qui bloque la remontée du CO₂, est assuré par une couche de schiste argileux, appelée chapeau ou couverture, située au-dessus du réservoir. Les forces capillaires qui retiennent le gaz dans les espaces interstitiels de la formation peuvent aussi contribuer au piégeage physique.  2, record 1, French, - pi%C3%A9geage%20physique
